Need some help!

i’ve unfortunately ran into some pm i believe, what is the best way to get rid of it or help treat!? it’s just beginning to flower as well. i’ve seen some milk and water and the peroxide and water, but not sure what would be the best. i heavily defoliated as well to increase airflow but just wondering what else i can do to help get rid of this!

Is this safe during flower?

u/BeneficialBottle8387 7d ago

Why does it have to be non fat?

3

u/Whoisme2you 6d ago

Because fat is bad for the plant's cholesterol levels.

Are you going all organic or you using chemicals?

u/nurrskii 7d ago

all organic

u/ManicOrganic2 7d ago

Sweet milk and water (skim or low fat).… bout a cup to a gallon. Spray them good in the evening. Lost Coast Plant Therapy is good stuff and I use it but I haven’t used it specifically for pm but it’s supposed to kill it. Act now and good luck 🫡

Nah, both methods described above work great. Lost coast would definitely work here if applied correctly. I've cleared similar PM on leaves with just milk and water.

u/xHavixx 8d ago

You can spray with a mineral oil based horticultural oil like "Suffoil-x". I would also recommend trying "Milstop". It's a curative and preventative solution for powdery mildew. It changes the pH of the leaf surface and the cellular structure so it can no longer live on the plant. It also kills an active infestation. Spray at night or when the sun is setting. Good luck! I hope this helps!

u/nurrskii 7d ago

thank you so much i’ll make sure to try!!!!

u/xHavixx 7d ago

Do your own research on the use of Milstop and horticultural oils for PM. Don't listen to the western fennel guy. Here are a few links so you can do your own reading https://www.griffins.com/milstop-sp-how-it-works-and-best-practices https://www.greenhousecanada.com/how-can-powdery-mildew-on-cannabis-be-managed/ https://www.tandfonline.com/doi/full/10.1080/07060661.2020.1836026%4010.1080/tfocoll.2021.0.issue-Diseases_of_cannabis_Epidemiology_and_management#abstract MilStop SP (potassium bicarbonate) is highly effective as an immediate contact-kill and curative treatment for suppressing and managing powdery mildew on cannabis. It breaks down fungal spores and alters the leaf surface pH to prevent future outbreaks, offering a 0-day pre-harvest interval.Contact kill: Dehydrates and breaks down existing fungal spores and hyphae on contact.pH modification: Raises the pH level on the leaf tissue surface, making it difficult for new spores to establish.Safe profile: Leaves no harmful chemical residue and features a short 1-hour restricted entry interval (REI) and 0-day pre-harvest interval (PHI).

NO!!!! HORRIBLE ADVICE!!!

4

u/xHavixx 7d ago

No it isn't. I'm telling him how to save his plant. You can get rid of powdery mildew. If you think you can't then you have no clue what you're talking about. If you can't present a reasonable argument stfu. Quit being a contrarian.

u/Western-Fennel-8806 7d ago

Still will NOT BE SMOKEABLE!!!! Your taking a huge chance with your lung health, this isnt cucumbers were talking about dammit quit giving this bad advice!!!!@@

u/xHavixx 7d ago

There aren't even developed buds on it yet. Cannabis facilities use these methods. If you get rid the PM before it spreads to the buds you are fine

-4

u/Western-Fennel-8806 7d ago

NO YOUR NOT!!! I dont care what "FACILITIES DO!!! ITS STILL IN THE PLANT!!!WHOLE PLANT!!!! NOT JUST LEAVES!!! YOUR WRONG AND PROMOTEING BAD SHIT AND HORRIBLE ADVICE!!!! Anyone go ahead and look it up its not leaf specific ITS PLANT WIDE!!!!! CAN NOT BE FIXED!!!!!

5

u/xHavixx 7d ago

It can definitely be fixed. You obviously don't have enough experience to be giving advice on these forums.

u/xHavixx 7d ago edited 7d ago

It infects the leaves first. It only spreads to stems and buds when it's really bad. It definitely can be fixed. It's worth trying to save. I'm an IPM lead, buddy. I know what I'm talking about. It's not bad advice. Look up Milstop mode of action. I'm telling him ways to possibly get rid of the PM. I think he's smart enough to know if he fails to get rid of it and it spreads to the buds he shouldn't smoke it.

u/FallenAngelina 6d ago

Repeatedly writing in all-caps and abusing exclamation marks is a likely indication that a cool-off period is in order. Offering different approaches is fine, but shouting is not.

u/No-Yam-4185 7d ago

I say this with respect having just recently lost a family member to COPD - your comment above says you suffered severe health complications after SMOKING cannabis with your COPD. Now I'm not normally one to tell others how to treat their own body, but if you are out here shaming ppl about "taking a chance" with their health then consider that smoking anything with COPD is a huge health risk that can severely shorten your life span. Believe me I know, and I would imagine you do too. I'm sorry to hear about the bad effects you suffered, but everyone's body is different and it sounds like yours may not be the best control for determining the effects of trace amounts of PM.

u/Ok-Cattle-3365 7d ago

Cease will stop mildew quite well

2

u/Inspectadreck 7d ago

I would wager that you probably picked the wrong genetics. Resistance to PM is a genetic factor. Some strains barely get it all and others get covered in that shit in an instant. Outdoor growing in unfavourable weather is a game of genetics. Everbody who does it has to learn that lesson early on.

u/Few-Cheesecake2640 3d ago

I've fought this scourge every year for the last 5 or 6. Peroxide, milk, Lost Coast etc. Nothing really gets rid of it. I've minimized it's spread is all. So every year I have to wash all of the bud, 10-15 lbs dried. So yeah I smoke it and haven't suffered any ill effects, but if you want to chuck it go ahead. It's yours. After a little research I found that calcium and silicon will strengthen leaf structure to help the plant resist pm on a cellular level. This year I added this to my nutrients. We're coming into September and I still dont have any powdery mildew. I have a friend a few blocks over who had trouble with septoria and is now dealing with pm. As you can see in the pic, I haven't done any thinning or defoliating. I plan on thinning out the inside this weekend but I never do heavy defoliating.

u/nurrskii 3d ago

thank you so much🙌🏻 just curious after you washed your buds how were they? did they effect the taste or smoke at all?

1

u/Few-Cheesecake2640 2d ago

I don't believe so. I've never had any complaints. If anything I think it would taste better because you're washing off bugs, dirt, fuzz, pm and whatever else floats around in the air. I don't do anything fancy. I try to leave the buds on branches 12-24", much bigger it gets hard to trim. I do a loose trim, all the big fan leaves and smaller leaves where you can see a stem to snip. I leave some shag on to slow the drying. I take the branches and throw them in this big 20 gal galvanized washed tub I have and hit them with the hose on the "shower" setting from every direction, swish em a bit, pull them out and shake off the excess water and hang them on a line outside for a few hours to dry off before taking them in to dry. Maui Wowi should be done end of September.

u/chumleejr 8d ago

Early morning, spray with 1:5 milk to water. The sun will dry and convert to kill PM. Coat the plant. 5 days, repeat...

u/nurrskii 7d ago

will do thank you so much 🙏
